The goal was to research the order of the effects, not the messages. That said, I didn't know Trick Room had two different ending messages. (The actual goal of finding the end of turn effects is complete now.)

maybe I just misunderstood

Not the most important, but not too hard: Could someone test the boost to water moves provided by Sea Incense?
Smogon has it listed as 20% like most other type boosting items, but both Serebii and Bulbapedia list it as 5% which would be consistent with some other Incenses (Lax gives +5% Evasion), and avoids having two insences with exactly the same effect.

happily ever after

Hmm, just discovered something weird with U-turn and Choice Items. This was in Pearl Doubles Battle Tower.

So anyways, I have Moltres, Azelf, and Milotic left. Moltres and Azelf both know U-turn, but only Moltres has a Choice item (Choice Scarf). The AI has Grumpig and Wigglytuff out (final Pokemon:I KOed the rest already).
I have Milotic and Moltres out.

Moltres used U-turn on Grumpig (60%-ish damage)
Switched to Azelf
Grumpig used Psychic on Azelf (minimal damage)
Milotic used Recover
Wigglytuff used Sing
Milotic fell asleep
--------------------
Azelf used U-turn on Grumpig
Switched to Moltres
Grumpig fainted (this is normal for U-turn)
Milotic is fast asleep
Wigglytuff used Dream Eater on Milotic (minimal damage)
Wigglytuff regained HP (or whatever it says)
--------------------
And then this is the weird part. I click Overheat on Moltres, and I get this message:

"The Choice Scarf allows only the usage of U-turn!" (or something like that, I can't remenber exactly, but it's the usual message when you try selecting a un-Choiced move on a Choiced pokemon.

Odd, because I U-turned out before U-turning back in. Has this happened to anyone before?

Fast-moving, smart, sexy and alarming.

If the Pokemon is put to sleep turn 1 (by a faster Spore, for instance) and then uses Sleep Talk, Sleep Talk will obviously select Last Resort. At the time Last Resort has executed, all other moves will have been selected at least once. Will Last Resort fail or succeed?

My prediction is that when Last Resort checks for "all other moves" having been used, the one it doesn't check is the one you selected (i.e. Sleep Talk in this case). To verify this, first use Last Resort while awake. Then, get put asleep, and use Sleep Talk. Does Last Resort work?

That test doesn't exactly test it. It's possible, although not likely, that Last Resort could fail the first turn you're using Sleep Talk. As in, Last Resort first turn, next turn Sleep Talk while asleep, and then see if Last Resort works.

Well on the topic of last resort, how exact does last resort check if all the moves are used?? Does it see if you've selected, move1, move2, etc. before using last resort, or does it check if the other moves you have access to have been used by the last resort pokemon??

Do you have to select all the other moves successfully in order to use last resort?? Example, Could you use hypnosis, fail, then use last resort (if you only had those 2 moves)

Or could assist or mirrormove another move you already have, then use last resort?? Example, you had a smeargle with Assist, Last resort, and Seedbomb (just as an example), if assist picked seed bomb off another poke could you use last resort on the next turn?

Another one, if you had a poke with u-turn, and u-turned into another poke with only u-turn and last resort, could you use last resort the following turn?? I think this might work in D/P but not Pt.

One of Sudo or Haunter's results has to be wrong, so I'd like them to comment on that.

It's based on whether you've used the move, not whether you've selected it. Also, the mechanic of U-turning to a pokemon counting as an execution of U-turn by the pokemon who is sent in is still in Platinum (see, e.g., Disable). What was changed in Platinum was that Choice Items reset their locks when using U-turn now; the mechanics of U-turn were not changed in this regard.

Anyway, before we decide what to test next (if anything) with Last Resort, we need to know which one of Sudo and Haunter was wrong. Of course, a third person is free to do the original test described in Obi's post as well:

Imagine a Pokemon with two moves:

Sleep Talk
Last Resort

If the Pokemon is put to sleep turn 1 (by a faster Spore, for instance) and then uses Sleep Talk, Sleep Talk will obviously select Last Resort. At the time Last Resort has executed, all other moves will have been selected at least once. Will Last Resort fail or succeed?
